1) Hit ratio for each buffer should be greater than 95%.
2) If hit ratio is less than 95%, no swap should be there.
3) Current usage of extended memory should not cross 75%.
4) We have to check the swaps for each buffer. For program buffers it should be 10000 hits/ day & for other buffers it should be 1000 hits/ day.
5) We have to check the free space & the free directory for each buffer.
In ST06/ST06N,
1) Ideally CPU should be free for 60% of the time.
2) Page out/s should be 0.
3) Under LAN, we have to check for collisions & errors. They should be 0.
4) We have to check for the SAPOSCOL status.
NOTE: These are very generic guidelines and may not hold appropriate for all kinds of SAP Systems. For example, on production systems, we expect better performance then other systems or Sandbox systems may experience more buffer problems. With a bit of variation, these will hold correct for most of SAP Systems.
